摘要
对煤层灰分进行分析的经典方法包括从钻孔取芯,然后在化验室化验分析得出结果两个步骤。为了克服单纯使用实验室分析煤芯采取率低,钻探岩粉对煤样的污染等产生的误差,采用定量的测井数据来计算煤层的灰分,可以在现场快速评价煤质。同矿区同一煤层的形成条件基本稳定,煤中灰分所吸附的放射性物质与煤层灰分含量有关,利用煤层的自然伽马值和煤层灰分进行回归分析,求出回归方程,并计算出煤层中的灰分。
The classical methods of analyzing coal ash including two steps,of which are core drilling and then laboratory analysis.In order to overcome the error of low coal core rate and drilling rock powder on coal pollution because of the simple use of laboratory analysis,using quantitative logging data to calculate the seam of ash can evaluation coal quality rapidly.Coal mine on the same floor is stable,the radioactive material adsorbed by coal ash is related to the coal ash content,using the coal gamma value to conduct regression analysis,find the regression .
